Bunsen burner design

In the design of a Bunsen burner, it is desirable to have the maximum range of volumetric flow without encountering stability problems. What, then, is the... 

A heating mantle has a hemispherical cavity that is used to heat round-bottom flasks. A Bunsen burner is designed to burn natural gas. Bunsen burners are useful for heating high-boiling point liquids,...

In-depth physical examinations of new composite component designs for aircraft interiors have contributed to the need for improved materials, as well as upgraded flammability testing. For example, the standard Bunsen burner test did not adequately determine the flammability characteristics of medium-sized composite parts when exposed to a hidden heat source that might represent an in-flight fire threat. Industry leaders are working with the FAA to develop foam... 

Plans are afoot to have the low-level requirements of MVSS 302, which is a Bunsen burner test on horizontal specimens, upgraded, since, in the latest car models with their compact designs and electronic door locks, the outbreak of a fire needs to be delayed for longer than has been the case. In addition to this, the new 42V electrical systems will also place increased requirements on fire safety perhaps up to UL94 V-0. 

Bunsen burners may be used to prepare capillary micropipettes for thin-layer chromatography or to prepare other pieces of glassware requiring an open flame. For these purposes, burners should be used in designated areas in the laboratory and not at your laboratory bench. 

For industrial purposes different designs of furnaces are used for combustion of chlorine in hydrogen. An essential feature of all these furnaces is the Bunsen quartz burner (see Fig. 113) which consists of two quartz pipes. A narrower one being inserted into a wider one and both covered in a steel casing. 

Burners are convenient sources of intense heat. The maximum attainable temperature depends on the design of the burner and the combustion properties of the fuel. Of the three common laboratory burners, the Meker burner provides the highest temperatures, followed by the Tirrill and Bunsen types. 

Bunsen designed a special gas burner for his spectroscopic studies. This burner, the common laboratory Bimsen burner, produces very little background radiation to interfere with spectral observations.
